"To all whom it may concern. p Be it known that I, LnwIsE. MoRRIsoN,

a citizen of the United. States, andresident of Newark, in the county; of Essexand, State of Ne\v Je11sey, -have: invented certain new and useful improvements in Printing Presses, of which; the? following is a specifircation.

-l his invention relates to printing presses, and the object of the invention is to. improve certain parts .of the mechanisml for. trans ferring the paper to. the platen. disclosed in my U." S. Letters vPatent. Number 1,393,036

dated October l1,-1921..

-Accordingly,myinvention is embodied in a mechanism fori thetpurpose set forth and arranged :as' hereinafter described andnas illustrated in the accompanying drawing in which v Fig. 1 isa-side-view of the paper trans- :terningmechanism of anautomatic '1' 'ob press with parts omitted andbroken away.

Il ig. 2 is a development in plan viewcf certain of the parts shown in Figure 1.

ll ig'. 3 is a detail View showing amodification. I V

Fig;- 4:-is anotherdetail view showing a still further modification -oftheadevice.

As disclosed inthe said patent, the improvement relates toian automatic; job press of the type known as a Chandler 8c Price job press, and concerns the means 'forautomatica'lly transferring the paper to' the-platen after the-paper or sheet has been separated fromthejpile. 7

Reference is; hereby made to the said. patentfor a more full anddetailedidisolosure of the invention. The particularmechanism referred to is-called' in saidpatenta transferring. mechanism and consists {of V a hinged table. or-frame which receives the. single separatedsheet and from which frame the sheet is thereafter. run olfonto the platen.

The frame'is hinged to a paper supporting table; which in turn'is' hinged to the press so as to be raised away from the press or lowered into operative relationship with the press mechanism. iVhen the'paper sppporting and. other mechanisms, including the transferring frame,-are raised, they may be swung to one side of the press so that the latter may be hand fed or for other purposes.

This raising and lowering feature is to be considered in connection with the present invention. In thesaid transfertable there-is provided a shaft which is rotated and over which and .in contact with which ,the sheet of paper is runofiionto the platen. Thepa-rticular object of this iiwentionis to provide novel and improved .meansafor rotating the said: shaft. c .Referringto-thedrawing, the frame ofthe pressris markedB andjthe platen 6,-pivot-ed to the. frame. at 5. .The. paper 52 rests on a paper support- 4 1 .'mounted on the feed table 24. .The latteris'pivotedat. 21 to a suitable bracket 22. By means oflevers 28 and 31 I .thefeed. table 24 maybe raised from the nor- 'mal-position-shown in full lines inthe drawing toithe elevated position shownindotted lines. I

:The' transfer table is represented by an arm 83.pivoteditoflthe"feed table atSLand" carrying theshaft' Si, it. being understood that .thereis-anarm'83 on: each side of the ,pressand that the shaft 84 extends from .the one side to the other. i

All of the above-described. parts are identical withithesanie parts disclosed in the said patent, :and asaimatter of reference, the numerals used in this-specificatio1r to identi fy said parts-are similar-Ito thoseuse'd in the said patent.

Asshown in Figure lihe-rein the separated sheet of papenlid-ropsi on the transfer table 83 and as the: shafts i rotates; it causes the sheet to be run off=onto the platen. The =-sl1aft84is driven fromthe usual @pl'aten locking cam 12,- which-is-well known :inathe art.

Referring to Figures 1 and 2 itw-ill be seen that the sh aft 84 is extended outside the part 83rand carriesaipulley: 7. .The aforesaid pivot :81 is inthe. 'fGIlIlTOfE arody which extends parallel to theshaftiSl. Qn the end .of said rod 581; there is; mounted a double pulley 84 .9 Wlth-i a space between the; two rpulleys. 8 and" 9, 1 andwonathe: hub i0 ofvsaid double i-pnlley is pivoted i an. arm ll'whichwis free; to swing on lsaidihubE 10.

The lower, free, end of the arm 11 carries a larger pulley13 to which is suitably secured a driving wheel 14. A belt 15 runs over the pulleys? and 8, and another belt 16 runs over the pulleys 9 and 13.

The driving wheel 14 is arranged to be held in driving contact with the cam 12 to be driven from the latter and if found necessary, both the wheel and a portion of the parts are in the position shown in full lines in Figure 1 and it will be seen that the said cam may be provided with meshing grooves 17 and 18 for better driving contact.

From the foregoing it will be clear, that when the press is operating, the shaft 84 will be rotated to run off the sheets to the platen. Again it will be observed, that when the paper feed table is raised as shown in Figure 1, the transfer table 83 and the arm 11 may be swung upwards in over the feed table 24;

I and rest there and these parts then do not obstruct any other parts of the press, nor interfere with making ready, hand feeding or other operations.

Means are provided for obtaining automatic frictional driving contact between the driving wheel 14 and the cam 12. On one side of the press, the paper feed table 24 carries a pin 20 which enters a socket in a standard 25 and thus supports the table 24: when it is lowered. On said standard 25 there is mounted a plunger 26 which is urged to wards the platen by a spring 27. The arm 11 is provided with a bearing surface 29 forming a notch as shown.

lVith the press operating automatically,

springpressed plunger 26 presses the driving wheel 14 into good driving, yet yielding, contact with cam 12. When the arm 11 is lowered from the position shown in dotted lines in Figure l (or lowered from the same position on an already lowered feed table 24), the extreme end of the arm comes into contact with the end of the plunger 26, and as the arm11 slides into position, the plunger automatically engages the bearing sun face 29 as will be understood.

The arrangement shown in Figure 3 indicates a coiled spring 32, the end 33 of which presses against the arm 11. The spring is coiled around the rod 81.

In the arrangement shown in Figure 4, the plunger 34 may be pulled away from the arm 11 by means of a knob 85. In this case the plunger is formed with a finger 36 which engages the arm.

If desired the arm 11 may be swung upward into the position shown in .dotted lines in Figure 4 and rest on a small laterally sliding member or latch 40.

It has been found that with the mechanism herein disclosed, a positive drive is obtained for the transfer table shaft 8 1. That the several parts are quickly moved out of the way when it is desired to gain access to the press adjacent thereto.

I claim 1. The combination of a press, a rotatable disk thereon, paper transferring means, a shaft in the same, a double pulley carried on said transferring means, a belt for driving said shaft from one of said pulleys, and means pivoted on said transferring means and in frictional driving contact with the said disk for driving the other of the said double pulley.

2. The combination of a press, a rotatable member thereon, paper transferring means, a shaft in the same, means for driving said shaft from the said member comprising a plurality of pulleys and belts for driving the same, a wheel held in frictional driving contact with said rotatable member, said wheel being arranged to drive one of the said pulleys.

3. The combination of a press, a rotatable member thereon, paper transferring means, a shaft in the same, means for driving said shaft, a double pulley on said transferring means, a belt for driving the said shaft pulley from one of the double pulleys, an arm loosely pivoted on said transferring means, a pulley and drive wheel on said arm, a belt for driving the other of said double pulleys from the pulley on the said arm and means for holding said wheel in frictional driving contact with said rotatable member.

1. The combination of a press, a rotatable member thereon, a paper feed table, paper transferring'means, a rod for pivoting the latter on said paper feed table, a shaft in said transferring means, a pulley on said shaft, a double pulley mounted on the said rod, a belt for driving the first named pulley from said double pulley, an arm pivoted on said double pulley, a pulley and driving wheel on said arm, a belt for driving the double pulley from said last named pulley and automatic operated means for holding said driving wheel in contact with the said rotatable member to be driven therefrom.

5. The combination of a press, a paper feed table, a rotatable member on said press, paper transferring means, a shaft in the same, mechanism for driving said shaft from the said rotatable member, said mechanism being arranged to be swung upwards away from said rotatable member and brought to rest on the said paper feed table.
